Can the 3155 ATO run time be adjusted?

[Macca_75]

Morning,

I've recently replaced my sump with a newer one. The return section is smaller and as such the ATO is firing off more often, for shorter time periods.

Is there a way to set the pump to "over deliver" for 15-30 seconds to stop it coming on as often?

Thanks in advance.

If it was made since 2012 you could turn up the pump speed so it delivers more in the 5 seconds it overfills, but the overfill time cannot be adjusted.

Thanks Roger - I'll crack the unit open and have a look but I think the unit is far older than that.

If it is a lot older, a new unit may solve the problem as the oldest ones didn't have the 5 second overfill. The oldest ones though did always run the pump at maximum power so the flow adjustment would not help.
